这是我第一次工作并尝试淘汰 js，但我无法让它工作。我正在做的是显示从数据库返回的列表/集合 - 基本上是所有用户及其信息的获取。

问题： 到目前为止，我没有让数据显示在页面上，也不确定我做错了什么或遗漏了什么。如果我缺少任何其他有助于解决我的问题的代码，请告诉我。谢谢！

查看您的代码，我想您正在使用 ASP.NET WebAPI。我认为您应该将您的 ajax 调用地址从 更改/api/RosterApiController为/api/RosterApi.

Both ASP.NET MVC and ASP.NET WebAPI have routing convention that except controller name without Controller suffix.

I think Slawomir solution is definitely something you should be aware of but you can try to populate your RosterUsers using a foreach.

_.each(data, function(user){
    self.RosterUsers.push(new RosterUserObject(user));
});
